Details
Precision-engineered to bring race-proven braking performance to V-Twins, the Kraus RTX8 Brake Calipers deliver superior stopping power, control, and feel—whether you're carving through the canyons, pushing limits on the track, or dealing with the unexpected on city streets. Precision-machined from race-grade billet aluminum, our calipers minimize weight. Compared to an OEM H-D front caliper, our calipers are 27% lighter. You'll experience a noticeable improvement in lever feel and feedback. Comes standard with Kraus RT-S Street pads, with optional Kraus Performance and Race pad upgrades available.
The RTX8 caliper is engineered for sustained, high-performance braking, featuring a five-bolt design that maximizes stability under load. Built for extended use, its two-piece construction integrates a finned backing to enhance heat dissipation, while four stainless steel pistons regulate thermal transfer to keep brake fluid temperatures steady. This results in unwavering stopping power and consistent performance, lap after lap, mile after mile.

*Final bleeding procedure required for optimal performance. (See Instructions)
**Kraus Calipers are pre-bled using DOT4 brake fluid. Riders planning to use DOT5, please call for alternative assembly.
Bleeding Brakes:
Kraus has taken the necessary steps to allow for an easier installation compared to any caliper on the market. Each caliper is pre-bled in-house, though a confirmation bleed is still necessary. Featuring re-engineered styling, we’ve incorporated an outboard bleed nipple and banjo take-off, making bleeding and installation easier while allowing fluid to fully circulate the caliper.
